A Baltimore Sun investigation documented evidence that three cameras have been erroneously issuing tickets, and the city is now looking into a fourth camera.

During a 5-minute news conference on the issue, the mayor told reporters several times that the camera error rate was less than 1 percent, but that figure is based on the number of known errors and not on a comprehensive review of the system.

"We put additional things in place, checks and balances, trying to figure out exactly where those breakdowns happen and put more resources there so we can reduce the less than 1 percent to zero," Rawlings-Blake said.

The mayor put together a task force to review her speed and red-light camera program. Half of the eight-member group are city employees. The panel only has the power to advise the mayor.

California's largest wildfire is spreading quickly, consuming 54,000 acres in three counties and staying active throughout the night -- a time when firefighters typically make progress, a state fire official said Sunday.
